.To all whom t may concern.'

Be it known that I, WALLACE CLrNToN RICHMAN, a citizen of the UnitedStates, residing at Butte, in the county'V of SilverboW, State ofMontana, have made a certain new and useful Invention in ConcreteBuilding is a specification.

This invention relates to concrete .building structures. f

lhe object of the invention is to provide a concrete building necessityof preparing aspecial foundation therefor.

A further object of the invention is to provide such a buildingstructure wherein sagging or derangement due to the absence of a specialfoundation therefor or due to settling or lifting of the usualfoundation 1s prevented.

@ther objects of the invention will appear more fully hereinafter.

The inventionl consists substantially in the construction, combination,location, relative arrangement of parts, and mod tion, all as will bemore set forth, drawing, and finally pointed out pended claims. I

This slab is formed with concrete in suitablemolds, and, if desired, may be reinforced by embedding within the bo y tereof at various points suitable relnforcing rods as indicated at 6,while in course of being molded into (the desired shape. ln moldin theyboards or slabs of concrete boards of this structure, whether d or not,in the erection of buildings, the site for the building or the groundwhere the walls thereof are to be erected is leveled od, and

t e line on which the Wall is to e erected. The slabs or boards requiredo orm a wallfor the building are then rest upon l)the e use of a cinderbed his purpose, owever, is not necessary. A steel rod 9 extending theentire width of the wall is placed within the groove 7 in the lower endsof the slabs or boards. This ma be accomplished y placingi the rod on eground or e, where a bed is used, and then placing the slabs or boardsinV upright position t occupying the of the boards.

if desired, a cinder bed 8 v1s placed along h tendency are bent orclamped over and around or otherwise secured to the horizontallydisposed rods 9 at the upper and. lower ends respectively of thevertical slabs or boards. The grooves 7 in the vertical. side edges otthe 'boards or slabs containing the vertical steel rods 10 as well asthe horizontal end grooves containing the rodsv 9, may be lled withcement or grout. ,In this' manner the vertical walls of the entirebuilding may be quickly erected, and the interlocking or connectingvertical and horizontal steel rods afford an efficient 'bracingwhichresists any of the walls sagging at one or more points even should thefoundation on which lthe wall at that point is erected recede. By

constructing the entire building inthe manner above described it will beseen and understood that the slabs or boards take thecompression'strains while the interlocked or interengaged vertical andhorizontal rods take the tension strains.

It will be readily seen that in like manner a flooring or roof may alsobe constructed andl its parts united in the manner 1 above described,and the rods of the roof,

for example, may be interlocked with the ends of the trussing of thevertical walls of the building by interengaging the tie rods of the roofslabs or boards with the ends of the vertical rods in the wall slabs orboards.

' ing edges of the slabs,

It will also be seen that the rods are entirely concealed and protected,being located within grooves formed in the side and end edges orsurfaces of theboards or slabs and embedded in the grout with which saidgrooves foundation for the buildingy need be constructed.` L

lIn Figs. 1 and 4 I have shown an arrangement of the slabs suitable forthe flooring or ceiling of a room. In this casethe longitudinal grooves12 inthe edges of the slabs aropen to the side surface,preferablyl theupper surface of the slab when applied in a floor or ceiling so thatwhen the two slabs 1 are positioned alongside and adjacent each other anopen groove as shown most clearly inl F ig. 4, which groove is partially"filled with concrete and thefilling is completed with a suitablecomposition, indicated at 13,

of tar pitch, or the like, which-forms an ex cellent finish to renderthe joint waterproof.

In the case of a iooring, these slabs are simply placed on `the ground,or other suitable support, within the space inclosed by thel walls. and.as above indicated, the tie rods in the end and edge grooves thereof areinterlockedorvattached together and to the tie rod system of thevertical wall boards.

In the case of a ceiling employing the slabs, the latter are formedadjacent their ends, as indicated at 14, with grooves or seats whichreceive the upper ends of the tical operatiog is formed at the meet`wall slabs, as shown in Fig. 1. In this case tie rods, if desired, maybe omitted.

Having now set forth the objects and nature of m invention, and astructure embodying the vprinciples thereof, as well as 7 the method ofcarrying the same into pracwhat I claimas new and useful, and of my owninvention, and desire to secure by Letters Patent, is y 1. In a concretebuildingstructure, a wall 7 formed of concrete boards or slabsvertically disposed in side by side relation, a tie rod common to all ofsaidv boards and disposedV beneath the lower ends thereof, asimilar tierod common to all of the boards and carried 8 by the upper ends of saidboards and verti2 cally disposed tie rods interposed between andinclosed by the proximate edges of adjacent boards, said vertical andhorizontal tie rods being interlocked together.

2. In a concrete building structure, a wall consisting of a plurality ofconcrete boards ldisposed in vertical position and in side by siderelation, said boards having .vertically disposed grooves formed intheside edges 9 thereof and horizontally disposed grooves in theltop andbottom ends thereof, a tie rod received in the horizontal grooves at theupper ends of the boards and .common to all of said boards, a like tierod received in the 9 grooves at` the lower ends of the boards andcommonto all'of said boards, and vertically disposed tie rods locatedwithin the vertical grooves in the side edges of the boards to beinclosed by the side edges of adjacent boards, said vertical andhorizontal tie rods interlocking together with each other to form abraced trussed structure.

` 3. In a concrete building structure, a wall consisting of a pluralityof concrete boards 1 dlisposed in vertical position and` in side by siderelation, said boards having vertically disposed grooves formed in theside edges thereof and horizontally disposed grooves in the top andbottom ends thereof, a tie rod 1 received in Fthe horizontal grooves atthe upper ends of the boards and common to all of said boards, groovesat the lower ends ofthe boards and common lto all of sa1d boards, andvertically 1 alike tie rod received in the disposed tie rods locatedwithin the vertical grooves in the side edges of the boards to beinclosed by the side edges of adj acentboards,
